Now JSC “PNITI” has a wide experience of working of semi-finished products from titanium and zirconium alloys, corrosion-proof and heat-resistant steels.
For the enterprises of the nuclear industry JSC “PNITI” has developed a production of high-precision semi-finished products of pipe parts (sleeve) for the subsequent cold rolling with the following parameters:
| Outer diameter, mm | 30…105 |
| Wall thickness, mm | 5…15 |
| Length, mm | 700…4000 |
| Variations in wall thickness overall length, mm, no more than | 0,4 |
| Roughness of external surface, Ra, no more than | 1,6 |
| Roughness of the internal bore, Ra, no more than | 0,8 |
Parts are made with use of the high-performance equipment, such as a radial forging machine. Possibilities of our equipment allow to manufacture workpieces as close as possible to a ready part. There is a possibility of production of parts of variable cross-sections.
The combination of the available equipment for boring of pipes with the subsequent radial forging allows to produce a pipe practically of any standard sizes. Besides, after carrying out forging operations mechanical properties of parts are improved by 40%.
JSC “PNITI” has a license for the right of production of the equipment for nuclear power plants and objects of a nuclear fuel cycle. Among our partners, there are such large enterprises as JSC “ChMZ” (Glazov), JSC “MSZ” (Elektrostal), etc.
